Did you know that Twitter, facebook and YouTube are blocked in China? The government doesn't allow their citizens to use those networks. This kind of control and denial of rights is getting harder and harder to pull off in a world of transparency, collaboration and sharing. China is very controlled and I don't believe that they should be deprived of using social media. I disagree that China blocks everything. But I did notice that most people who ban things like this do It for a reason.
